Sorry - hit send too soon

223,000 miles 2003 MDX

AC stopped working AC Diagnostics showed nothing. Garage suggested Climate Control Module bad. Replaced climate control module with new (used) one- AC working well. Responds to temperature change /rear working fine.

Problem is that the front fan speed control not working. Unit does not show on LCD and the fan does not respond. AC On/Off responds , Mode responds just not the blower speed control.

Any ideas ??? Thanks

Also have an 84-1 code VSA /!\ problem going on. I’ll research that more.

Thanks

Thought same, but same model number on unit and the fan speed varies when on automatic.

Wondering if there is a separate circuit for manual speed control - doesn’t light up on LCD screen.
